SASH-FASTEN ER.

SPECIFICATION forming part of Letters Patent No. 747,619, dated December22, 1903.

Application filed August 26, 1903. Serial No. 170,868. (No model.)

To aZZ whom it may concern:

Be it known that I, ADOLPH F. W. LORIE, a subject of the King of GreatBritain, residing at Dunedin, New Zealand, have invented certain newanduseful Improvements in Sash- Fasteners, of which the following is aspecification.

My invention relates to the form of sashfastener disclosed by me inapplications for Letters Patent of the United Stated filed July 2, 1902,Serial No. 114,130, and July 29,

My present invention consists in the features and combination andarrangement of parts hereinafter described, and particularly pointed outin the claims.

' In the accompanying drawings, Figure 1 is a front view of theinvention. Fig.2 is a side View, partly in section. Figs. 3, 4,.and 5are detail views. showing a modified form of locking means.

In the drawings, 1 indicates a strip to be secured to the face of theside rail of the upper sash. This strip or plate I show as pro-v videdwith dovetail-shaped ridges 3, extending transversely thereof from edgeto edge, said ridges or corrugations forming abrupt or sharp shouldersor ridges for contact therewith of a holding device, which I prefer toemploy, in the form of a screw-bolt or rod 4, working through a nut 5 onthe upper edge of the meeting-rail 6 of the lower sash. The screw-boltis provided with a quick-acting thread 8, extending from its forward endalong the same andengaged by a rib or projection 9, cast'on the interiorof the nut, so that the turning of the screw will cause a longitudinalmovement of the same. The screw has a reduced end, with a stop-ringlOloosely held thereon, so as to turn, and thus provide for even wear ofsaid stop. In order to operate the screw, I provide a coil-spring 13Fig. 6 is a perspective view.

For retracting frame to within easy reach of the hand, the

upper end of said chain extending over and around a wheel 14, grooved toreceive the chain, the point of connection of the chain to the wheel'orother part having a curved bearing for the chain being shown at 15. Bypulling the chain the screw is turned and retracted, so that its stopend is withdrawn from contact with the plate or strip on the upper sash,and consequently the sash or sashes may be moved into the requiredposition, and then by releasing the chain the spring, exerting itsforce, will automatically turn the screw, so that the same will be setinto locking position. In order to supplement the locking efiect and tohold the lower sash firmly locked when closed, I provide means wherebywhen the screw is set in looking position at the time the lower sash isclosed the lower sash will be automatically locked in said closedposition. This looking means in one of its forms comprises a bracket 16,having a base-plate 17, screwed to the Window-frame, and provided withan arm 18, extending outwardly therefrom, said arm being curveddownwardly and outwardly.

The chain-wheel has a projection 19 on its innor face arranged in suchrelation to the axial center of the chain-wheel and to the curvedstop-arm that when the lower sash is closed the said projection will bein such position relative to the curved arm as to describe an are underthe said arm or within its inner edge. It will be understood that inclosing the lower sash the screw-bolt must be retracted out of line withthe corrugations on the plate, and the chain being pulled for thispurpose will turn the wheel, so that the lug willbe in position to passdown outside the outer end of the curved arm and to a point just belowthe horizontal plane thereof, and then upon releasing the chain thespring will turn thescrew into looking position, and at the same timethe ing or projection of the wheel will move on the circle and along theinner edge 20 of the curved arm until it abuts against the edge orsurface 21 of the curved extension, which thus acts as a look. Inreleasingthe fastener the movement of the chain-wheel to retract thescrew will turn the projection or lug awayfrom engagement with thelocking or stop arm. By the use of the screw-fastener and thissupplemental lock or fastener both of the sashes will be held locked,even though the upper sash may be open. In such case the two sashes willbe locked together by the screw, and the lower sash will be held againstmovement by the locking-arm. Were the locking-arm not used to hold thelower sash, of course the two sashes might be raised a distance equal tothe distance the upper sash is lowered; but the locking-arm will preventthis.

In order to prevent the chain from being reached and used by a person onthe outside of the window when the upper sash is lowered, I fasten thechain, so that it cannot be drawn out through the window for operatingthe lock, and for this purpose the locking-bracket is provided with afoot-piece or projection 22, slotted at 23, and when the lock is set thechain is simply given one turn about the projection or foot-piece, so asto rest in the notch, which will hold the chain securely against beinggrasped by an implement or device in the hands of a person outside thewindow.

For a like purpose I provide a swell 30 on the bracket, which lies withits face sufficiently near the groove of the chain-Wheel as to shieldthe chain and prevent the insertion of an instrument or wire to graspthe same.

Instead of the form of lock above described consisting of the brackethaving the curved arm I may employ a gravity-hook 24 of substantiallythe same form as disclosed in my applications referred to. This lock ispivoted to a bracket 25, attached to the window-frame, and it is inposition to engage the spindle of the screw-bolt when the lower sash isclosed, and its engagement with said spindle is automatic, for whichpurpose its upper edge is inclined, so that as the sash is closed thespindle striking the inclined edge will push the gravity-hook aside, andthe weight 26 on the said hook will return the same into lookingposition. In order to release thislock at the same time the screw isretracted to disengage the corrugated or other bearing part, I providean eye 27 on the gravity-hook and a second eye 28, slightly oifset onthe bracket, and I employ a cord or chain 29, extending from the mainoperating-chain above mentioned, through the eye 28 and attached to theeye 27 of the gravity-hook, so that when the main chain is operated toretract the screw the same action will cause the gravityhook to be swungaside, and then the sash may be raised.

It will be seen that both forms of lock are controlled by the operationof the hand operating connection.

I claim as my invention- 1. In combination, in a sash-fastener, a nut, ascrew working through the same to engage a part of the window, a lockfor said screw comprising a part on the frame and means for operatingsaid screw and simultaneously controlling the lock manually,substantially as described.

2. In combination in a sash fastener, a

nut, a screw working through the same to engage a part of the window, alock for the sash, and means for turning the screw, said locking meansbeing automatically set by the rotation of the screw in one directionand being automatically released by the rotation of the screw in theopposite direction, substantially as described.

3. In combination in a sash -fastener, a not on one sash, a screwworking through the same to engage a part of the other sash a lock forone of the sashes comprising a member on the frame and a hand operatingconnection for the screw extending vertically of the window-frame,saidoperating connection controlling also the lock substantially asdescribed.

4. In combination, in a sash-fastener, a nut, a screw working throughthe same to engage a part of the window, a lock for the said screwcomprising a turning member, a curved bearing on the screw-shaft and aflexible op erating connection extendingaround the said bearing, saidconnection controlling both the screw and the locking member,substantially as described.

5. In combination, in a sash-lock, a nut, a screw working through thesame to engage a part of the window, a curved bearing on the screw, alocking member carried by the said curved bearing, a locking-arm fixedto the frame and means extending over the curved bearing for operatingthe same.

6. In combination, in a sash-lock, a nut, a screw working through thesame, a grooved wheel on the screw, a laterally-projecting locking-lug,a. chain or cord for operating the grooved wheel and an arm on the framefor engaging the locking-lug, substantially as described.

7. In combination, in a sash-fastener, a nut, ascrew working through thesame, a flexible connection for operating the screw and locking meansfor the flexible connection, substantially as described.

8. In combination, in a sash-fastener, a nut, a screw, a flexibleconnection for operating the screw and a lock for the said connectioncomprising a foot-piece or projection about which the flexibleconnection may be wound, said projection having a slot to receive saidflexible connection, substantially as described.

9. In combination in a sash fastener, a nut, a screw, a curved bearingon the screwspindle having a groove therein, a flexible connectionextending over the said curved bearing and attached thereto, and ashield extending in close proximity to the groove of the bearingsubstantially as described.
